This design might need some adjustments and I will update the design if changes are made, but as of now it seems to be correct.
Plenty of jigs out there that help form a good circle and to drill the holes but I always have problems getting the bends at the correct angles for my configuration.
It took me about 8 different prints to get the design where it's at now.
If you have a Duet Smart Effector with a Slice Engineering's Mosquito hotend attached or E3D's V6 and want to use a 'Berd-Air' type of layer cooling solution. Then this might work for you too.
I had the Berd-Air 24v kit, my pump broke (not the motor, the motor does spark a lot) after about 8 months of use and I looked into brushless motors with an air pump. I found one and works great. I usually have it at 25% power. I listed below if you want to go that way.
In this design are the
pipe mount for E3D V6
pipe mount for Slice Engineering's Mosquito
pipe form jig
drilling hole jig
Bending jig A remix of "ShadowX" Berd Air Tube Bender Fixture (Inside Diameter: 12mm)
1 M3 nut for the 'Drilling Hole Jig'
1 M3 x 10mm bolt for the 'Drilling Hole Jig'
K&S Engineering 8101 Round Aluminum Tube 3/32" X .014" X 12" (My local hardware store carries 3/32" x 3' long aluminum tubes for under $3).
Nidec DC12-24v Brushless Air Pump
You can use PETG and ABS too.
I didn't need supports but with some printers you might need to.
